4-2-1 manifolds for 1.3SR

[garyc]

Has anyone got any pictures of any 4-2-1 manifolds. Any information on who makes them or where they are available from would be helpful too.

[Stuart]

off topic, where in hertford?

so i can avoid you lol


on topic

try www.raldes.co.uk for an ashley manifold and system (4-1)
or www.eurorallye.co.uk same kinda thing

[garyc]

Thanks for that I've seen them already, I am looking for 4-2-1 not 4-1 manifolds.

[j1400]

The difference being?

[Stuart]

there are very few places that supply 4-2-1's for novas, unless you make one or get one specially made.

[dan_mk1]

What is the difference? summin to do with more torque lower down the rev range on the 4-2-1??

[srs1]

or go to a scrappy and get one off a nova gte/gsi sr or sri depending on your car.

[Stuart]

a 4-2-1 can give 5% more low down torque but you might lose/not gain at top end

a 4-1 loses 5% low down and gains more at top end.

you could use the std 4-2 cast manifold and twin down pipe setup i guess

[garyc]

Would prefer proper tubular job rather than cast std part. Thanks for the info so far.

[rgv_stu]

a 4-2-1 is good but the primary runners on the cast jobbie arnt really long enuf

[j1400]

Waht I mean is youi probably wont notice any difference between the two types, but a general improvement over the cast manifold. Have had both on my engine I can say I havn't noticed much differnce, except the 4-1 has free'd the engine lots over 6k which was resticted with the 4-2-1 I had on it. janspeed 4-2-1 and a hand built ashely 4-1. I noticed no mid range/low end differences. an ashely 4-1 would be fine and they are good value for money.

I want a 4-1! they only do a 4-2-1 for the clio :evil:

[Ste_Nova]

i've got a 4-1.... cant wait to move it over onto the 1.6 8v engine then get it rr

[Philsutton]

the sr has a 4-2-1 as standard doesnt it?

[Snowface]

yes sr's have 4-2-1 as standard.

So going from a standard 4-2-1 sr manifold to a 4-1 Ashley/janspeed will improve power a bit? but lose torque low down

correct?

[Stuart]

*bing* correct
